hi, came onto pc about a hour or so ago and internet had red cross on it, went into device manager and no network adaptors are showing, the ethernet port on the pc only has a yellow light on no green light, ive tried reinstalling the drivers had no effect, been into bios and checked nothing has changed and even tried loading defaults aswell, found a wireless usb stick to be getting on with but its not the best, really stumped as to whats happened, the pc mobo is asus p5q , its getting on abit now must of had it 5 years, anyone know what i can try to get it going ? thanks
